System Overview

The Sievers InnovOx On-Line TOC Analyzer consists of eleven major modules (see Figure 1):
1. Multistream module, which accommodates two or five sample streams, depending on the Analyzer
configuration. It also includes a vial port, which is used to calibrate the Analyzer. The multistream
module also includes a port through which a check standard can be measured.
2. The sample pump accessory (shown in Figure 1) can be used to draw sample water to the multistream
module from sources that are not pressurized.
3. Sample handling module, which draws sample into the Analyzer and mixes the sample with acid,
oxidizer, and dilution water. When NPOC is measured, the sample is sparged in this module.
4. Gas control module, which controls the flow rates of carrier and sparge gas.
5. The Air Purifier Accessory removes CO
the Analyzer can produce carrier and sparge gas from dry, oil-free compressed air.
6. Reactor module where organics are oxidized to CO
• Reactor tube
• Heater and cooling fan
• Peristaltic pump
• Valves
7. Gas-liquid separator, where carrier gas, containing CO
entering the nondispersive infrared (NDIR) detector.
8. NDIR module, containing an aerosol filter and the NDIR detector.
9. System/controller board (not shown in Figure 1), which contains:
• Microprocessors and circuitry
• Ethernet and USB data outputs
• Color video graphics array (VGA) display with touchscreen
• Flash memory card
10. Input/Output (I/O) board (not shown in Figure 1), which contains 4-20 mA analog outputs and digital
inputs and outputs.
11. Power Supply/Power Entry (universal), which is not shown in Figure 1.
